MCU-32型分布式摸块化自动测量系统

1.用途

MCU-32型分布式摸块化自动测量系统适用于单台或多台组网自动采集各类传感器的测量数据，广泛应用于大坝及水工建筑、铁路、道路、桥梁、港口、隧道和工民业建筑物等的自动化监测系统。

系统基本构成

系统由若干支各类监测传感器、若干台MCU-32型分布式摸块化自动测量单元、可选择的某类通讯网络、计算机系统及软件组成。

主要特点

开放式结构，摸块化组合，可采集频率、电压、电流、电阻、开关量、脉冲量、数字量等电量，测量精度高，系统稳定可靠，具有较强的抗环境电磁干扰和抗工频干扰的能力。

每台MCU-32为摸块化组合，由四个任意组合的测量摸块﹑主控摸块、通讯模块，电源模块及接线端口组成。

MCU-32有完善的防雷防静电及瞬变脉冲阻断功能的设计，高压脉冲由阻断电路先行阻止，再由吸收电路安全吸收，确保模块运行安全。传感器安全保护功能，在测量闲置时自动将传感器进线短路并接至系统地线上，确保传感器安全，无需另配避雷器。

具有完备的系统自检功能，MCU-32每天会自动检测一次各部件的工作状况，发现故障立即报告。每个摸块上有12个工作状态指示灯，将随时显示电源、测量、收信、发信、各通路的工作状态。

MCU-32有多种数据传输方式：RS485传输、无线数传电台传输、光缆传输、电话网络、以太网络、公共移动网(GPRS/CDMA)等。

MCU-32具有灵活的采集数据处理方式，可以工作在自报方式、召测方式、单机存贮方式等多种方式的组合，内置4M字节存贮器可以存贮传感器满接时单点7000次采集数据，并且所有存贮结果均采用文本方式存贮。存贮的数据可通过串口传输至计算机，也可以使用U盘转拷贝到计算机，增加了数据转移的灵活性。

简单易操作的系统软件，功能有：在线测量(单次采集，连续采集) 、定时测量、离线测量 、越限报警、数据库管理(SQL Server大型网络数据库)、成果输出(表，图)等，所有界面和菜单均为全中文版。

Product Information

Modular Distributed Automatic Measuring Apparatus (Type: MCU-32)

Product Description

The type MCU-32 modular distributed automatic measuring apparatus (MDAMA) can be applied to acquire and monitor the data generated by sorts of sensors. The MDAMA is not only able to work independently; it can also work cooperatively with other MDAMAs through networking. With the water proof, lighting protection, and anti-interference abilities, MDAMA can perform its work in a wide-rang natural environment. The main functions of MDAMA include networked and distributed measurement, single time measurement, time-interval multi-times measurement, continuous measurement, timing measurement, automatic data collection and storage, communication with computers, threshold alert, data management, figures/tables generation, manual-comparison measurement, and etc.

Product Speciality

l Open Architecture, Modularization, High Resolution, Stable Reliability, anti-EMI, and anti-Interference of Power Frequency.

l Broad Measurement Range and Monitoring Applications: Voltage, Current, Resistance, Capacitance, Frequency, On-off, Pulse, and etc.

l The modules, such as the measurement module, the main control and communication module, the power module, and the interface module, may be freely combined to suit for individual requirements.

l Improved lightning and electrostatic protection, and transient pulse block function. The high voltage pulse can be blocked by the protection circuit firstly, and then absorbed by the absorber circuit, which may ensure the safety of the built-in modules. Sensor protection function is all provided in MCU-32 MDAMA, thus the surge arrester is not necessary.

l Improved self-checking and malfunction reporting function. The MCU-32 MDAMA can check the operating status of the components automatically everyday. If an error is found, the alerting service will be activated. Moreover, 12 LEDs on the panel of each module also indicate the real-time operating status.

l Supporting diverse data transmission methods, such as RS485, TCP/IP, wireless data transceiver，Tele-transmission, wireless network transmission (GPRS/CDMA).

l Flexible data acquisition modes, such as the automatic measurement and reporting mode, the remote measurement mode, and the local storage mode. With the built-in 4MB disk, the MDAMA can store up to 7000 * 32 data items. The data can be transmitted to the computer through the serial port or copied by a USB flash disk.
